Vincent SP-311MK with vintage Klipsch???

[mness4]

I'm planning to revamp my HT setup with a main focus on music, and I'm looking for some opinions on my plan to power the L and R. I'm running a 5.1 HT system with parallel sets of vintage Klipsch for each of the fronts and center (parallel Chorus+Chorus II for each of the L and R, and a pair parallel Forte II as the C...I know, it's a strange arrangement, but it really fills the room.) So each looks like 4 ohms. The rears are single Quartets. I'm running a Marantz SR7001 with an Adcom GFA-5503 powering the L, C, R. The rears run straight into the Marantz. I'm planning to replace the SR7001 with a SR7008 (the 7001 has been going into protect mode on startup...99.9% sure it's not related to the speaker arrangement.)

My thought is to move the 5503 to the C and rears and get a Vincent SP-331MK to power the L and R channels. This should vastly improve 2-channel listening. Does anyone have any experience powering vintage Klipsch with the Vincent? I heard a McIntosh the other day (granted, not with Klipsch) and fell in love. I would like to think it's a tube thing and not necessarily a McIntosh thing. Granted, it was a $50K setup, so that might be wishful thinking.

Thanks,

Mike
